三维扫描重建女性生殖系统模型在胚胎移植培训中的应用

目的探讨三维扫描重建技术在胚胎移植培训中的效果。方法用三维扫描仪、数据处理软件EXScan-Pro、3D打印机重建出标准及子宫颈内口狭窄两套女性生殖系统模型。对20位临床及实验室人员进行废弃胚胎的模拟移植培训教学,并对培训前后胚胎种植部位准确性、胚胎移植操作时间以及更换移植导管的频次进行统计和评价。结果胚胎种植部位准确性得分由(0. 60±0. 41)分提高至(1. 37±0. 29)分(P<0. 05);胚胎移植操作时间由(340±146) s缩短至(180±59) s(P<0. 05);更换移植导管的频次由(0. 83±0. 37)次下降(0. 23±0. 13)次(P<0. 05)。结论三维扫描重建女性生殖系统模型应用于胚胎移植教学培训,能有效增加操作者正式上台手术前的实践经验,提高胚胎移植技术实施的稳定性,也有利于建立规范的操作流程,是传统观摩和带教方法的有益补充。

Application of three-dimensional scanning in rebuilding female reproductive system model for embryo transfer training

Objective To explore three-dimensional scanning and reconstruction technology in embryo transfer training. Methods Two sets of female reproductive system models,standard and cervical stenosis,were reconstructed with three-dimensional scanner,data processing software EXScan-Pro and 3D printer. Twenty clinical and laboratory personnel were trained to simulate the transfer of degenerated embryos,and the accuracy of embryo implantation site,the time required for embryo transfer and the frequency of replacing the transfer catheter before and after the training were evaluated. Results After training,the accuracy score of embryo implantation site was increased from 0. 60±0. 41 to 1. 37±0. 29( P<0. 05);the time required for embryo transfer was shortened from( 340±146) s to( 180±59) s( P < 0. 05);the frequency of replacing the transfer catheter was decreased from( 0. 83 ±0. 37) to( 0. 23 ± 0. 13) times( P < 0. 05). Conclusions Application of rebuilding female reproductive system model for embryo transfer training can improve the practical experience of operators prior to formal surgery,improve the stability of embryo transfer and help to establish a standardized operation process,as a supplement to the traditional observation and teaching methods.
